W. Gissing Pty. Limited, Newtown, near Sydney, New South Wales, Australia Application February 21, 1951, Serial No. 211,988 In Australia March 6, 1950 6 Claims. (Cl. 189-65) 1 This, invention relates to an improved weather proofing attachment for louvre windows, shutters or'the like, andhas been devised to prevent extreme driving rainfrom being forced between the respective louvre blade receiving channel fmembers and the vertical side members of the window termed jambs.

'It has been found in some known louvre windows that under very extreme conditions wind- .driven rain may pass through the narrow space between the respective louvre blade receiving channel members of the window and the said jambs.

An object of the present invention is to provide weather proofing means of the above nature which will overcome the above disadvantages.

A further object of the present invention is to provide weather proofing means of the above nature which are neat in appearance and which may readily be attached to existing louvre win-' dows.

The present invention may best be described by reference to a known louvre window or shutter in which the respective louvre blades are received at each end in channel members, the latter being'rotatably mounted with' respect to the jambs which are secured to the usual window frame; the known means for turning the louvre blades need not be referred to as it is not associated with the present invention.

. According to the present invention a weather proofing attachment is pivoted longitudinally with relation to each of the respective jambs.

The said attachment is adapted to bridge the space between the respective channel members and the respective jambs when the window is in substantially closed position.

In order that the invention may be more readily understood, reference will now be made to the accompanying drawings wherein:

Figure l is a detail elevational view looking from the outside and illustrating the type of window to which the present invention is applicable, the window being shown in its open position.

Figure 2 corresponds to Figure 1, but illustrates the known type of window in its closed position also looking from the outside thereof.

Figure 3 illustrates a weather proofing attachment in accordance with the present invention,

- looking towards the front side thereof.

Figure 4 is a view corresponding to Figure 3, but looking towards the inside thereof.

Figure 5 is a detail sectional plan view illustrating the weather proofing attachment in closed position.

Figure 6 is a detail sectional plan view corresponding to Figure 5 but with the louvre blades open.

Figure 7 is a detail view looking towards the left of Figures 5 and 6 and illustrating the weather proofing attachment in the open position of Figure 6 and illustrating spring means for returning it to the position seen in Figure 5.

Figure 8 is a detail perspective view illustrating the weather proofing attachment in the closed position. b

Figure 9 is a detail perspective view corresponding to Figure 8 but showing the weather proofing attachment in partly open position under engagement by the lower edge of the channel member.

Figure 10 is 'a detail perspective view corresponding to Figures 8 and 9 but showing the weather proofing attachment in fully open position under engagement with the side edge of the channel member.

Portion of a louvre shutter to which the present invention is applicable is illustrated in Figures 1 and 2 of the accompanying drawings, and in which one of a pair of jambs I0 only is shown together with portion of a window frame II to which the jambs H] are secured in known manner.

Each jamb l0 pivotally receives channel members l2 which support the respective louvre blades l3, the latter being capable of being placed in open position as in Figure 1 or in closed position as seen in Figure 2 in which latter position the blades ['3 overlap and lie in so called sawtooth formation.

In the closed position, it sometimes happens that there is a gap or small space M between the jamb l0 and the adjacent channel members l2, which it is desirable to cover when the louvre shutter is closed.

According to the present invention weather proofing attachments are pivotally attached to the respective jambs I0. In Figures 3 and 4, a weather proofing attachment is illustrated which is capable of being pivotally attached to the jambs In by hinges l5 the said attachment being of angular formation and having webs l6 and I1.

The web l6 has a saw tooth shaped edge l8 for engagement with the respective channel members I! when the shutter is closed, Figures 2, 5 and 8. It will, however, be appreciated that the said saw tooth edge I8 may alternatively engage the respective blades [3.

The web I 6 together with the web IT, bridge the gap l4 between the jamb l0 and-the respective channel members I2, when the said shutter is closed.

The respective weather proofing attachments are pivotally attached to the respective iambs ID in such manner as to be turned upon their pivots by the respective channel members 12 and 'to be returned to their normal closed position by mechanical means. To this end the pivotal means illustrated are hinges l5 which are carried upon the Web I! and are secured to the jamb H].

To provide mechanical means for returning the said weather proofing attachments during the act of closing the louvre shutter, a spring 20 is disposed in the jamb l and is connected by a link 2| to a hook 22 carried by the hinge 15, said spring 20 being also connected to the jamb H] by any suitable means such as a tongue 23 formed integral with the said J'amb 10.

It will be appreciated that the spring 28 il1ustrated is only one of the many ways that "the said attachments maymbe caused to return to their closed position following the closing movement of the shutter.

The. hinges 15* maybe spot welded to the web ll of. the water proofing attachment and removably secured to the jamb'lfl by a bolt 24 as seen infFigure 7. Infthis view an opening 25 is clearly shown through which the link 2| is passed from the spring20 to'be connected to the said hooked lug 22.

' In operation, assuming thatthe louvre shutter to which the attachment is fitted, is closed, as in Figures '2, 5 and 8, then, the weather proofing "attachment will bridge the gap l4, Figures 5 and 6, between the channel members l2 and the lambs).

If now the louvre shutter is opened from the inside in the normal way, the said attachment will be turned upon its pivot hinges !5' by the 'channelmembersl2, see Figure 9, and during the initial movement of thesaidchannel members I2, the lower edge 26 of the'respective channel members '12 will engage the web it and push by the side 2! of the respective channel members I i2 as seen'in Figure 10.

On closing "the louvre shutter the reverse operation takes place, but in this instance the web [5 follows the respective channel members 12 under mechanical action due to the spring 20; thus the weather proofing of the louvre shutter is effected in a more or less automatic manner.

I claim:

1. Ihe combination with louvre shutters having louvre blades mounted in channel members rotatably mounted upon a jamb, of an improved weather proofing attachment therefor, in which said weather proofing attachment extends across the space between the jamb and the respective channel members, and comprises pivotal means for longitudinally pivoting the said attachment with respect to said jamb, said attachment being adapted to-be turned upon its pivots by engagement between the respective said channel members and the said attachment in the act of opening the shutter, said attachment being returned to its normal position by resilient means.

. 2. The combination claimed in claim 1, in which said weather" proofing attachment is provided .--with-a saw tooth edge for engagement with; said channel members.

- 3. The combination claimed in claim 2, in which said weatherproofingattachment is turned upon its pivots during the'opening of the shutter by an-initial'engagement between the lower edge of respective channel members and the said weather proofing attachment and finally by engagement between the said saw tooth edge and the side of webs having the said pivotal means for the said weather proofing attachment.

6. The combination claimed in claim 1, in which said resilient means consists of a spring or springs.
